The U.S. Nuclear Regulatory Commission (NRC) issued a Regulatory Issue Summary (RIS) entitled, RIS 2002-22, Supplement 1, ``Clarification on Endorsement of Nuclear Energy Institute Guidance in Designing Digital Upgrades in Instrumentation and Control Systems.'' This RIS supplement clarifies RIS 2002-22, which remains in effect. The NRC continues to endorse Nuclear Energy Institute (NEI)-01-01, as stated in RIS 2002-22 and clarified RIS 2002-22, Supplement 1. This RIS supplement clarifies the guidance in RIS 2002-22 for preparing and documenting qualitative assessments that licensees can use to develop written evaluations to address the criteria in NRC's regulations for digital instrumentation and control (I&C) modifications. This clarification is intended to reduce regulatory uncertainty for licensees applying the process set in the NRC's regulations and making digital I&C modifications without prior NRC approval.

Clarification on Endorsement of Nuclear Energy Institute Guidance 
in Designing Digital Upgrades in Instrumentation and Control Systems

AGENCY: Nuclear Regulatory Commission.

ACTION: Regulatory issue summary; issuance.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) issued a 
Regulatory Issue Summary (RIS) entitled, RIS 2002-22, Supplement 1, 
``Clarification on Endorsement of Nuclear Energy Institute Guidance in 
Designing Digital Upgrades in Instrumentation and Control Systems.'' 
This RIS supplement clarifies RIS 2002-22, which remains in effect. The 
NRC continues to endorse Nuclear Energy Institute (NEI)-01-01, as 
stated in RIS 2002-22 and clarified RIS 2002-22, Supplement 1. This RIS 
supplement clarifies the guidance in RIS 2002-22 for preparing and 
documenting qualitative assessments that licensees can use to develop 
written evaluations to address the criteria in NRC's regulations for 
digital instrumentation and control (I&C) modifications. This 
clarification is intended to reduce regulatory uncertainty for 
licensees applying the process set in the NRC's regulations and making 
digital I&C modifications without prior NRC approval.

DATES: The RIS 2002-22, Supplement 1 is available as of June 25, 2018.

SUPPLEMENTARY INFORMATION: Supplement 1 of RIS 2002-22, ``Clarification 
on Endorsement of Nuclear Energy Institute Guidance in Designing 
Digital Upgrades in Instrumentation and Control Systems'' (ADAMS 
Accession No. ML18143B633), is intended for (1) all holders of 
operating licenses under part 50 of title 10 of the Code of Federal 
Regulations (CFR), ``Domestic Licensing of Production and Utilization 
Facilities,'' and (2) all holders of a combined license under 10 CFR 
part 52, ``Licenses, Certifications, and Approvals for Nuclear Power 
Plants.''
    In 2002, the NRC staff issued RIS 2002-22 to notify addressees that 
the NRC staff had reviewed NEI-01-01 and was endorsing the report for 
use as guidance in designing and implementing digital upgrades to 
nuclear power plant instrumentation and control systems. Following the 
NRC staff's 2002 endorsement of NEI 01-01, holders of operating 
licenses have used this guidance in support of digital design 
modifications implemented without prior NRC approval in accordance with 
10 CFR 50.59. The NRC inspections of documentation for these activities 
uncovered inconsistencies in the performance and documentation of 
engineering evaluations and associated technical bases for 
determinations on the 10 CFR 50.59(c)(2) evaluation criteria. This RIS 
Supplement clarifies the RIS 2002-22 endorsement of the NEI 01-01 
guidance by providing additional guidance for developing and 
documenting ``qualitative assessments'' that are used to provide an 
adequate basis for a licensee's determination that a digital 
modification will exhibit a low likelihood of failure to support a 
conclusion when applying the evaluation criteria set in 10 CFR 50.59, 
that a license amendment is not needed.
    The NRC published a notice of opportunity for public comment on a 
previous draft of this RIS in the Federal Register on July 3, 2017 (82 
FR 30913). Subsequently, the NRC published a second notice of 
opportunity for public comment on the revised RIS on March 14, 2018 (83 
FR 11154). As noted in the March 14, 2018 Federal Register notice 
(FRN), ``[t]he NRC staff engaged in multiple communications with the 
public and stakeholders and continued internal discussions about the 
RIS. As a result of these efforts, the NRC has substantially rewritten 
the RIS. Due to the extensive nature of these revisions, and in light 
of this additional opportunity for comment, the NRC is not directly 
responding to each comment received in the previous comment period.''
    The NRC received comments from seven commenters as a result of the 
March 14, 2018 FRN. The NRC considered all comments, some of which 
resulted in changes to the RIS, and discussed the evaluation of these 
comments and the resulting changes to the RIS in a memorandum that is
